动机--这项研究试图比较三种不同的方法来衡量指挥和控制情景中的情景意识(SA)。
研究方法--共有20名参与者在试验性指挥和控制试验台环境中进行了作战评估的第一个问题，即军事规划过程。参与者使用三种不同的SA测量方法：冻结探针法、试验后主观评价法和危急事件技术访谈法。然后在研究期间获得的SA测量之间进行比较。
结果/设计--结果表明，冷冻探头测量(SAGAT)是唯一与参与者表现有统计显著相关性的测量。研究结果还表明，所使用的三种SA指标之间没有显著的相关性。
研究意义--研究结果为Sagat方法在命令和控制任务中测量参与者SA时提供了验证证据，并表明这三种方法以不同的方式使用视图SA。
原创性/价值--本研究探索了在指挥和控制活动中对SA的测量，并对每种方法在此背景下的适用性进行了判断。
带走信息--类似于文献中提出的关于SA的不同理论观点，这些发现表明，比较的方法以非常不同的方式看待和评估SA。
Motivation -- This research sought to compare three different approaches for measuring Situation Awareness (SA) during a command and control scenario.
Research approach -- A total of 20 participants undertook question one of the Combat Estimate, a military planning process, in an experimental command and control test bed environment. Participant SA was measured using three different SA measures: a freeze probe technique, a post trial subjective rating technique, and a critical incident technique interview approach. Comparisons were then made between the measures of SA obtained during the study.
Findings/Design -- The results show that the freeze probe measure (SAGAT) was the only measure that had a statistically significant correlation with participant performance. The findings also demonstrate that there was no significant correlation between the three SA measures used.
Research Implications -- The findings offer validation evidence for the SAGAT approach when used to measure participant SA during a command and control task and suggest that the three approaches used view SA in a different manner.
Originality/Value -- The research explores the measurement of SA during command and control activity and makes judgements on the suitability of each method for application in this context.
Take away message -- Analogous to the different theoretical perspectives on SA presented in the literature, these findings suggest that the methods compared view and assess SA in a very different manner.
